Description
Did you know that you can have 6th gear in your Allison transmission just like the later model Duramax's with a mere swap of the valve body and transmission control module (TCM)? Its true, you too can benefit from a double overdrive, resulting in better fuel economy, reduced wear on your engine, and a better overall driving experience with a simple upgrade. Improve your LB7 or LLY's reliability by utilizing DuramaxTuner.com's own designed and tested kit coupled with their established transmission tuning. This is not merely a stock six speed Allison file, not even close! The tuning experts at Duramax Tuner calibrate both shift firmness and timing, so you'll be guaranteed to feel the smoothness and better shift quality missing on the 5 speed Allison. Furthermore, a huge benefit of adding another gear is that of the increased MPG's due to the reduction in RPM at cruising speed, which also reduces wear on critical engine components. Overall, your truck will run smoother at higher speeds with less RPM, giving you a broader powerband, more fuel economy, and a more pleasurable driving experience. IMPORTANT NOTE: This product requires an upfront core charge that will be reimbursed upon receipt of your original transmission control module. Once you have received and swapped out your original valve body and TCM, rebox the TCM into the 6 Speed Conversion Kit box and return to Duramax Tuner. Once they have received the TCM, they will notify us of the core return and we will promptly issue credit back to you. Because Duramax Tuner uses a brand new valve body, they have no need for you to return your original / core valve body, just the TCM.

Please agree to the Terms and Conditions to Defer the Core Charge, or Accept the Core Charge.
